Steve opened the fridge, and then watched Astrid walk up the stairs to get her dog. When she left Rogers went for the plate she left, and took a bite. It tasted really good... but then, everything he's eaten has tasted a lot better than the stuff he had in his old life. He gave Stark a look, then looked back down at his food. "What?" Stark asked. 

"Just give her space, alright? She doesn't need anyone interrogating her. She clearly didn't want any of this being told. We also know how you are with others." And with that he stood up, putting his plate in the sink, then making his way down to the gym. He watched Astrid punching the bag like he's done so many times. He walked up next to her, setting up a punching bag on to a hook with one hand a couple feet away from her. "The best way to hit is to keep your arms close to your sides, and up, to cover your head." Steve said casually, as if nothing happened in the room. He knew sometimes that talking about something doesn't help. He wrapped tape around his knuckles, giving a glance over at her. "Gives you a lot more agility, and defensive options." he added, making a few light jabs at the bag himself.
